Ok So what kind of wastegate is this. Is it anygood? should I keep it? will it do its job, what are the differences between the different brands. and what size spring is it?

 

It's a old school turbonetics deltagate.around 35mm ,you can use it if your low on funds but I wouldn't recommend it.. there more updated gates on the market now similar in size: turbonetics evolution,turbosmart and tial.

As far as the spring size most are marked with colors to tell psi rating

 

What could go wrong if I use it? What are benefits of new ones? Sorry noob

 

I want to be safe, I'm not doing this build to push my motor to the max
